Dry bulb temperature is the temperature of air recorded by a thermometer, when

A It is not affected by the moisture present in the air
B Its bulb is surrounded by a wet cloth exposed to the air
C The moisture present in it begins to condense
D None of the above

Correct Answer: It is not affected by the moisture present in the air

The Dry Bulb Temperature refers basically to the ambient air temperature. It is called "Dry Bulb" because the air temperature is indicated by a thermometer not affected by the moisture of the air.
